Some rumor, some fact, some... who knows...ArrivalBlueSS said:Has anyone put a cat back on their car and done any dyno testing?
I am thinking about putting one on and just wondering if I can expect any gains and how much.

2.5" seems to be the most 'tested' size for gaining power. Some mag, or company did some testing on 2.5" and 3" exhausts. Some people here have 3" and love it, some people here have a 2.5" and claim to have lost torque. So it's still in the air.
